Abstract:
A sudden increase in detrusor pressure after cessation of voiding detrusor contraction and in the absence of flow can be recorded in some cystometric tracings and has been defined as detrusor after-contraction. Although it has been described in medical literature since the late 19th century, no common definition had been found by the authors of the relatively few articles published on the subject. This review was conducted by analyzing the available literature on the topic in an attempt to understand its real significance and clinical impact and has revealed several controversial aspects to the problem of detrusor after-contraction. These aspects include its prevalence in various groups of patients studied urodynamically, its definition, and its clinical significance.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
